Application filed March is, 1920. Serial No. 366,7l28.

To all whom it may concern Be it known that I, WILLIAM V. BERGErI,

a citizen of the United States, and a res1-' adapted to be arrangedalong highways for indicating dangeror the need for caution, wherein avisual signal is provided capable of being seen in day-light and havingmeans a for illuminatingthe same through the reflection of theheadlights of an on-coming car to .be visible at night.

In the drawings:

Figure 1 is a, front view of the improved signal,

.Fig. 2 is a side View,

Fig. 3 is an enlarged section through the illuminating device.

In the present embodiment of they inventiona suitable standard'isprovided, in the present instance, a pipe 1 of suitable cross section,preferably having at the top a ca 2 and suitably anchored in the grounNear the top of'this cap there is provided a plate 3 secured to the pipeby any suitable means, indicated at 4, and ,this plate carries warninglegends indicated at 5, in the present instance, the words Slow down andRight turn.

Below the plate 3 is arranged a casing consisting of a parabolicrportion6 and a flaring portion 7 This flaring portion has at its free edge amarginal flange 8, and to this flange there is secured a ring,9 by meansof bolts and nuts 10, and the ring carries th head and shaft of therepresenta- -=tion 11 of an arrow extending transversely of the 45 Theinstance, Safety'first. A lens 13 is supported in the casing 67"by'means of a,

bezel ring 14 which engages the edge of the lens and has legs 15connected with the 0st. l iead and shaft of the arrow carry a legendindicated at 12, being in the present ably silvered or otherwisepolished on its inner surface.

It will be understood that this lens is ruby red, and the image of theapproaching lights will act as an illuminating means for illuminatingthe. lens to attract the notice of drivers of vehicles approaching thesignal. By actual test the li ht can be easily seen at adistance of 600and it is of especial advantage in that it requires no attentionwhatever, While it is always ready to show a warn-ing light when thesignal could not otherwise be seen.

The signals are arranged at suitable points, and they will act withoutfurther attention. The reflecting surface of the parabolic portion ofthe casing should be rust-proof ,and capable of withstanding all kindsof weather, and the parts must be so proportlonedthat the image may besharp on the reflector. v The face. of the ring 9 provides a surfaceupon which may be arranged advertising matter of. any desired character,and this surface as well as the legends on the plates 3 and the arrowwill be of baked enamel. I

I claim: A signal of the character specified, comprising a standard orsupport, a conical shell secured to said support, said shell flaringforwardly and outwardly and surrounded on its outer edge by a verticalring adapted to, carry traflicindicia, the flared portion of said shellpresenting an annular light ray collecting and deflecting plane surface,said conical shell having its apex portion-*curved to define a parabolicreflecting surface, a lens held at the focus of said parabola, thediameter of said lens being less than the diameter of the parabolic areaand spaced forward of the vertical plane of the juncture of the flaredand parabolic portions 'of the shell, whereby an annular pas sage isdefined between the lens and the shell to permit passage of light raysfrom the headlight of the approaching vehicle dee vice, which have beencollected and deflected by the plane surface" of the shell into theparabolic reflector and also received and reflected by the parabolicreflector to be re-.

flected forwardly through the lens to the approaching vehiclel 4 WILLIAMVREELAND B RGEN.-
